i i 4UNrrn "Tatras PATENT WILLIAM Jy. schwanz, or BROOKLYN, NEWYQRKQI .Application lileddanuary 8*,

To a/ZZ hwk/om rit may; cori/warn'.- v l g p Beit known that LWILLIAMJ. SCHWARZ, a j cltlzen of the United (States, vresiding at Brooklyn, in the'county of `Kings and State of New.- `York', have inventedcertain-'new and useful- 'Improvementsin- Gas-Stoves, of'which thelfollowing is a full and complete specification,

such as'will enablethose skilled in the artto Y. which it appertainstofmakeand' use the same.'

The object-of this invention is to provide an improved gas-stove designed for heating purposes only and vwhich fmaybevused in rooms or compartm'enf'gs v.wherever needed; and with this and otherfobjects in viewthe, invention consists in a gasheater or stove constructed as hereinafter described and claimed.

In the drawings forming part of this speciication, in which the separate parts of my improvement are designated by the same reference characters in each of the views, Figure 1 is a central vertical longitudinal'section of a stove made according to my invention, and Fig. 2 a vertical section thereof on the line 2` 2ofFig.1. l rl In the practice of' my invention I provideagas-stove which comprises a hollow bottom base portion d and a supplemental. hollow base portion b, mounted thereon, and said base portion a, is providedat the corners withl legs a?, and the sides thereof are dared-out# wardly and downwardly, and the top base por-i tion b, which is in full communication with the bottom base portion d, is provided Witha 'central longitudinal tubular casing which is arranged concentricallyin said top base portion or centrally thereof, as clearly shown in Fig. 2, and the front of the bottom base,-

' portion is provided with any suitable air-register a3. Passing longitudinally Athrol'igh the bottom base portion is a pipe d, whichisclosed at one lend and provided at the other end with a coupling dhaving an air-valved3 and a nozzle-coupling d4, wherebya flexible gas-su pply pipe may be connected therewith, and the coupling d2 and the air-valve d3v are of the usual construction, and said tubed constitutes the burner or burner-tubeof the device and is provided on its upper side with openings di, through which the gas escapes into the bottom base portion aand at which point said gas may be ignited.

Arranged over the top base portion d are 19012. serial Noreaser. en minis i a plurality of:vertical hollowcylindricalgcasf -ings'are'incommunicationatthe base thereof" f e are closed at the top bya horizontal flatandj ings @,four of which]areshowfn",4 and theseica'se,

with theLtop-:base portion-b, andsaid 'easingsf-4 hollo'wgtop member f,'fwhic`h is provided with; s a supplemental'hollowtop`membergwhich l v, ispreferably provided withy a` 'vertically-arf' ranged front" g2,hav'ing lair-outlet openings L g3,'andthe supplementaltop{member `gdsj lalso,preferably*provided with a topvandback` f' f5 y portion, whichis. segmental in cross-section, l aff'f as shown at g4. L 2 165.*3L Passing vertically through 'the hollowcy-V f lindrical casingse at each end of thestove are pipe ymembers h,`,which communicate at their upper ends with the hollow horizontal top member f and at their lower ends'with 7o A a horizontal tubular casing c in the top'base 'l portion b, and intermediate of the tube members h aretwo other vertically-arranged tubes and j, theupper ends of which arein comf f 'munication with the supplemental horizontal 75 Y v top memberc/.andv the lower ends of which are in communication with the tubular cas-f ingsc the base member b. The tubular casing c inthe base member'b is'also divided centrally and vertically bya 8o."

partition lt,- and the vertically-aman ged tubu-v larmembert'- is provided'at its lower endwith y.a ight-angle extension, which is curved to l, the right and which passes throughsaid "par- 'tition, yand bynmeans of thisconstruction three of the vertically-arranged tubular mem-- bers within the cylindrical casing @,includ- `ingthose designated by'thelrefcrence char. s

acters 1I andj,fare in communication with thel y .y Y right-hand endportion offthe tubular casing 9o cinlthefbase membervb, whilethe other verl Vtically-arrangedtubular member hin the lleft-hand vertically-arranged,cylindrical casing e is in communication withthe Aleft-hand l f endlpf vsaid tubular casing ein' the base mem- 95 ber.

The hollow cylindrical and vertically-ar-v ranged casings e are also provided, preferably near the top thereof, withe'scapejports orpasy v sages m for the hot gases of combustion, andl Ioo in Fig. l of the drawingsI have shown the separate parts of a stove or heater bound to# gether by vertically-arranged rods n, and a horizontal rod or rods o are also placed in the thereof.

The gas is ignited in the bottom base member a., aud the hot gases of combustion pass around the tubular easing c in the top base member Z) and up through the vertically-arranged cylindrical casings@ and escape out through the openings rm, and in this operation the tubular casing c and the tubular Vmembers 7L, t', and 7' in the cylindrical vertically-arranged casings e are highly heated. At the same time the air enters through the tubular port or passage p at the left-hand end of the top base member b and passes into the left-hand end ofthe tubular casing c, where it is heated, and from which it passes up through the left-hand tubular member 7L into the horizontal top m e1nberf,from which it passes downwardly through the right-hand tubular member hinto the tubular casing c, from which it passes upwardly again through the tubular members 'L' and j into the top member g and is discharged from the front thereof into the room or compartment. In this operation the air is highly heated, as will be readily understood, anda suitable conduit may be provided to convey the air to the ingress port or passage atp from any desired point, if desired, or the air may pass directly from the room or compartment into the tubular casing c through said port or passage p.

My improved heater is simple in construction and operation and may be used wherever devices of this class are desired, and changes in and modifications of the construction described may be made without depart- A ing from the spirit of my invention or sacrificin g its advantages.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gas-stove comprising a hollow base portion, vertically-arranged hollow casings mounted thereon and in communication. therewith, a hollow top portion placed on said vertically-arranged hollow casings and provided with a supplemental top portion having front openings, a tubular casing arranged centrally and longitudinally in the base portion and divided by a central transverse partition, and

tubular members arranged in said verticallyarranged cylindrical casings, all of which are in communication at their lower ends with the said tubular casing in the base portion and part of which are in communication With the hollow top member and the others of.

which pass therethrough and are in communication with the supplemental top member, substantially as shown and described.

2. A gas-stove comprising a hollow base portion, vertically-arranged hollow casings mounted thereon and in communication therewith, a hollow top portion placed on said ver` arranged cylindrical casings, all of which are in communication at their lower ends with the said tubular casing in the base portion and part of which are in communication with the hollow top member and the others withthe supplemental top member, said base portion being also provided with a burner-tube below said tubular casing, substantially as shown and described.

3. Agas-stove comprising a base composed of a bottom and top portion, the bottom portion of the base being provided with a gasburner tube, and the top portion of said base being provided with a horizontally-arranged tubular casing, a plurality of vertically-arranged hollow casings placed on the top base portion and in communication therewith, a horizontal hollow top portion placed on said vertically-arranged hollow casings and provided With a supplemental top portion which is placed thereon and provided with openings, vertically-arranged tubes placed in said vertically-arranged hollow casings, all of which are in communication at their lower ends with the tubular casing in the upper base portion and part of which are in communication with the top portion and others with the supplemental top portion, said tubular casing in the upper base portion being provided with a transverse partition through which one of said tubes passes substantially as shown and described. l

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 31stv day of December, 1901.
